Figure 15. Generation time of blocks for simulation program
A data visualization of further study on the number of data entries is illustrated in Fig. 16, and for the explicit, the data in first 300 minutes are only presented. Since the simulation program produces a current measurement data entry and a voltage one, the number of data entries stored in boosting station increases linearly. Meanwhile, when a new block is generated, the data produced in such new block generation process are stored in blockchain at once, hence a data synchronization between boosting station and blockchain happens. And that is the reason why the number of data entries in blockchain grows in a stepwise way. Furthermore, when a data summon event happens, the synchronization time would be advanced, so some “narrower” steps can be seen in the diagram of Fig. 16.
